Method for operating a tire inflation system of a motor vehicle and tire inflation system

Method for operating a tire inflation system of a motor vehicle, wherein the tire inflation system comprises a compressed air source which contains a compression device, a pressure accumulator from which inflation lines lead via an inflation valve and control lines lead via control valves from the control lines to respective tires via wheel valves, comprising the steps of:

• a) acquiring a set point tire pressure from operating variables;
• b) comparing the set point tire pressure with an actual tire pressure last measured and determining whether air is to be fed to or extracted from a respective tire;
• c) applying compressed air to the control lines via the control valves and wheel valves which are connected to the inflation lines via a rotational input means and is arranged on respective tires and is controlled by compressed air applied via the control lines and independently from the inflation lines;
• d) feeding or extracting air to the respective tires via the inflation lines during a specific time period without accompanying pressure measurement;
• e) measuring the actual tire pressure in the inflation lines and comparing same with a set point tire pressure;
• f) if the actual tire pressure does not correspond to the set point tire pressure, feeding to or extracting air from the at least one tire via the inflation lines during a specific time period without accompanying pressure measurement;
• and
• g) if the measured actual tire pressure corresponds to the set point tire pressure, the cycle in accordance with steps a) b) c) d) e) f) is not repeated again until after a specific time period or until a specific operating state occurs.
